I have a bunch of .45 ball ammo that's packed in 20 round cardboard boxes marked "20 Cartridges, Pistol Ball, Caliber .45 M1911, Ammunition Lot W.C.C. 1032, Western Cartridge Company".
The headstamps are FA32, meaning this stuff was manufactured in 1932.
It was given to me by a retired Army Major in the early 1970s. He'd stored it in his attic. In Tucson. Most of the time I've owned it, it's been stored in garages or attics in AZ, SD and FL. Temps ranged from -20 to +120 or more.
Now to my point. In 2008, I ran 5 rounds through one of my 1927 Argentine Colts and chronographed the results. I got an average of 842 fps and a Standard Deviation of 12!
Somehow I don't think leaving your ammo in the car for a few months is going to be a problem!!
